Brain hemorrhages are emergency medical conditions, with potentially life-altering ramifications. Immediately consult your veterinarian anytime your dog spontaneously loses consciousness, bleeds from the ears or nostrils, bleeds within his eyeballs or exhibits unusual postures. Additionally, sudden seizures, rapid breathing and blue-colored skin -- often indicative of poorly oxygenated blood -- are frequently associated with brain hemorrhages.
A variety of causes lead to brain bleeds. Head traumas often cause small vessels within the brain to rupture, as can tumors, parasites and some infections. Dogs suffering from high blood pressure are at increased risk of developing brain hemorrhages. Additionally, some toxic substances can lead to brain hemorrhages if ingested.
